NVD Description

Note: Versions mentioned in the description apply only to the upstream cilium-fips-1.19-operator-azure package and not the cilium-fips-1.19-operator-azure package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Cilium is a networking, observability, and security solution. From 1.19.0 to 1.19.4, standard Kubernetes NetworkPolicy specifications using CIDR-based ipBlock rules without pod or namespace selectors erroneously generate a wildcard namespace allow rule when Cilium is configured with a custom clusterName rather than the default any value. The parser incorrectly instantiates a pod selector on selectorless peer definitions, allowing traffic from other workloads in the same namespace as the subject of the policy. This issue is fixed in version 1.19.5.
